Frequently Asked Questions
Q: What is the 1313912 sealed bearing assembly?
A: The 1313912 is a maintenance-free sealed radial ball bearing assembly designed for manual pallet jack wheel and axle applications. It combines a high-carbon bearing steel housing with sealed ball races and double contact seals that prevent dust and moisture ingress. The assembly is pre-lubricated and requires no grease maintenance, making it ideal for harsh warehouse and cold storage environments.
Q: What are the material specifications of the 1313912 bearing assembly?
A: The 1313912 bearing features a high-carbon bearing steel outer race and inner race with hardened ball elements for durability under radial loads. The cage is reinforced synthetic polyamide, which resists corrosion and does not require metal cage maintenance. Double contact seals are press-fitted to the races, preventing water and dirt ingress while maintaining proper lubrication in the bearing cavity. This design extends bearing life in wet floors and cold storage operations.
Q: Which pallet jack models use the 1313912 bearing assembly?
A: The 1313912 sealed bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers. Verify the bearing bore diameter, outer diameter, and width specifications against your equipment manual or existing bearing to confirm proper fit. Sealed bearing design differs from open grease-packed bearings, so verify your jack uses sealed bearing assemblies before ordering.
Q: How long does the 1313912 sealed bearing last in warehouse use?
A: The 1313912 sealed bearing assembly typically lasts 3 to 5 years in continuous warehouse use, with lifespan depending on load conditions, floor surface, and maintenance. Heavy-duty operations with high push loads and rough floors accelerate wear. The sealed design provides longer life than open bearings in wet and cold environments. Replace the bearing when wheels become difficult to turn, make grinding noise, or develop excessive lateral play on the axle.
Q: What failure symptoms indicate the 1313912 bearing needs replacement?
A: Common bearing failure symptoms include grinding or squealing noise when turning the wheel, rough or jerky wheel rotation, lateral wobble of the wheel on the axle, or increased effort required to push the pallet jack. Seal damage allows water and debris into the bearing cavity, causing rapid corrosion and ball race failure. If the seal appears cracked or leaking grease, replace the bearing before extensive race damage occurs and affects truck handling and load control.
